Rebuilding an early Covel Type 15 Surface Grinder
Now, as well as I'd scrubbed the saddle beforehand, I didn't realize the traverse feed boss was removable.
I managed to get it loose and unscrewed, and found a great deal of old scummy oil inside.
Cleaned, stripped and scrubbed, it was then a simple matter to reassemble the whole unit as a "cartridge".
Then oil it up and slide the whole mess back into place. (After also cleaning out the saddle, too, of course.)
Then, at the underside, there's a setscrew with a thick brass plug used to tighten against the boss, to lock it in place.
Slide the handle on, since the nut, and we're done!
It's starting to look like a proper machine tool again. :)
Now, before the table goes on, these two rollers, on some sheetmetal leaf springs, are set into their oil reservoirs.
The rollers carry oil from the reservoir up to the table ways as the machine is cycled, keeping it well lubed.
The table and wings, which had been freshly scrubbed and painted, are ready to install.
Unlike the table of a milling machine, the surface grinder table just drops into place.
Finally, with enough of the loose parts reassembled, I was able to clean up
the work area enough to move the machine to a more convenient spot.
Note the cord leading to the motor, and the freshly-installed table wings.
The last few bits for the moment are things like this dust guard for the front edge of the table...
The grinding wheel arbor...
And a brand-new Camel 10" x 1/2" x 3" grinding wheel. The Covels of this vintage used to use a
now-obsolete 2-1/2" bore wheel, and at some point a previous owner simply sleeved it to take
now-common 3" bore wheels.
Then the table stop lugs...
And finally the two lock thumbscrews for the knee assembly. The left one locks (sort of) the
knee from moving, while the right one allows the pointer to be moved, in order to "zero" the dial.
